Holly has been Damien Thorn's nanny since the Thorns moved to England when Damien was a toddler.

During Damien's fifth birthday party, Holly comes across a Hellhound, which looks her in the eye and influences her into killing herself for Damien. Holly then travels up onto the roof of the Thorn estate and ties a noose around her neck.

Holly hangs herself.

She claims to Damien that it's all for him, then jumps from the roof ledge; hanging herself.
